the inactivity block is supposed to be random, but now that you mention it I realize that I changed it to check some debugging stuff and never changed it back! I'll fix that ASAP, I already have 1.0.1 in the pipeline for a minor bug fix, but I'll work on getting 1.0.2 up as soon as possible to address that and maybe modify some of the difficulty balancing so that, at least on easy, it's easier to see all of the phases.
